Applieation filed December 20, 1922. Serial No. 607,931.

To all whom it may concern:

Be it known that'I', Leo J. GRUBMAN, a citizen of the United States, and a resident of the borough of Bronx, county of; Bronx, city and State of New York, have invented certain new and useful Improvements in Articulative S ound-Producin'g Devices for- Dolls, Etc ofwhich the following is a specification sufficient to enable those conversant with the art to which the invention appertains to utilize the same.

My improvements relate to the type of soundproducing devices designated priniarily for'incorporation in toys, and espe cially dolls, etc., in, which the production of articulatory syllabical sounds in imitation of the human voice is the object to be attained, substantially in the manner set forth inmy concurrent applicationsfor patents on the same subject, Serial No. 542,884, filed March 11th, 1922, and Serial'No. 601, 725, filed November 16th, 1922; As in both of the said concurrent applications, the main object of my present invention is the production of simple, substantial, compact, self-contained mechanism of the character designated, which is gravity-automatic in operation in that the use of springs is obviated, as well as the necessity for extraneous. pressure for sound production, the specific object of this inventionbei'ng-the variation, regulation, and perfection of the syllabized expression, and the facilitation of operation." To this end the invention consists in the specific combination, arrangement and construction of parts and appurtenances herein described and claimed'distinctive features being the means provided for modifying sound emission, and for avoiding retardant inflation of the air compression chamber, all as hereinafter fully set forth. v

I herein exemplify in the accompanying drawings a practical and preferred embodi ment of the essential features of my invention, without, however, limiting myself to the identical form and construction of parts shown, because changes may be made: in minor details with the attainment of like results, and without departing from the spirit and intent of my invention in this respect.

The operative parts of my sound producing device are, as heretofore, enclosed in a rigid casing, consisting, in the preferred form shown herein, of a cylindrical shell 0, closed at one each of what is designated for convenience of description asthe basic disc '0, a'nd at the other extremity by an inter- Fig. 3, an elevation of the closed end parts, and to afford fixed external dimensions, in such manner as to render the device, considered in a unitary sense, self-contained, and without protuberant parts other than the head of the nasal throttle valve as hereinafter set forth. Thus it is obvious that the shell or casing c, 0, 0 might be other than cylindrical in shape extraneous with substantially like results, although the form shown herein is preferable, on account of its simplicity, compactness, and cheapness of structure.

The head plate 0 of the casing is intersticed, or formed with one or more apertures 0 for communication with the atmosphere, but such apertures 0 may be formed elsewhere in the casing, if desired. As shown herein, a series of these air ports or perforations 0 are located in the head plate 0 of the casing as indicated more particular in Figs. 2, 4-, 5 and 9, of the drawings, provision thus being made for the free inlet and outlet of air, and the emission of sound vibrations emanating from the interior of the device, as hereinafter set forth.

The wind chest or sound emission pipe a, which also functions as a guide and lateral support for the free ormovable head I), of the bellows B, which, in this construction, constitutes the air compression chamber, is likewise preferably, but not necessarily, of cylindrical form, and positioned centrally as related to said bellows and the casing, it being fixedly secured to and between the base plate 0, and the head plate 0 as shown more particularly in Figs. 5%, 5, and 9, of the drawings. Thus, it may consist of a tube (1, held in place at one extremity by being seated in a depression 0', in the base plate 0', and at the other extremity by the inner medial edge 0, of the head plate 0 fitting in an annular groove a, (Figs. 4, 5, 9, 10, and 11) formed for the purpose in the periph eral surface of said wind pipe a, adjacent to the end thereof, the extreme outer edge of the tube being peaned or bent over the outer surface of said head plate 0 thereby looking the said wind pipe (2, securely in place.

This extremity of the throat or wind pipe (1, is closed by the nasal valve J, the hollow cylindrical portion '25, of which extends into the wind pipe 0, as shown more particularly in Figs. 9 and 11, of the drawings, fitting snugly therein so as to make an air tight joint therewith. The other extremity of said wind pipe (1-, is closed and held in position by the aforesaid depression 0, in the basic disc 0.

.Vithin, and adjacent to this end of the wind pipe a, is positioned a reed r, or equivalent sound producing element, the side of the tube in proximity thereto. and betweenit and the inner side of the basic disc 0, being formed with one or more apertures as a through which communication is established with the interior of the bellows B, so as to afford adequate means for the admission of air to, and its expulsion from, the air compression chamber of said bellows B, according to circumstances, as for instance for the inflation or deflation of said bellows B, always effected through said wind pipe a.

Air is admitted to or ejected from the wind chest at, through the medium of the primary or nasal aperture a and the secondary or aspirate aperture a both of which communicate under certain conditions, with the space 0*, between the intersticed head plate 0 of the casing and the resonator or sound intensifying partition P, which latter is rigidly positioned within the casing and is related to said head plate 0, as shown more particularly in Figs. 4, 5 and 9, of the drawings.

Said resonance partition P, is preferably of concave form on the side thereof opposed to the intersticed head plate 0 of the casing, as shown in the drawings, so as to concentrate and align the sound waves or vibrations emanating from the wind chest a, in a manner essentially parabolic, although I do not limit myself in this respect, since the main function of said partition P, is to definitely limit the sound productive area of the device and separate it from the rest of the interior of the casing, it having been found that otherwise the collapse of the bellows B, causes the movable head I), thereof to attenuate the sound vibrations by enlarging the area between it and the perforated head 0 thus interfering materially with and modifying the sound production in such manner that the second syllable produced is less distinct than the first.

The said resonator partition P, is formed with a central opening 19, for the accommodation of the wind chest at, and it may be affixed to the casing in any suitable manner, preferably by the method set forth in my last named concurrent application Serial No. (.=i,'i'25, which also describes the means here in shown for effecting the permanent attachment of other portions of the device, said details of construction forming no part of my present invention.

in this connection it may be stated that the lll'lPlOVGIIlBlliT-S herein sought to be covered relate especially to the means for controlling the intake and outlet of air to and from the device in such manner that complete inflation of the air compression chamber is assured, and also whereby the device may be adjusted to pronounce syllabically either the words papa or ma-ma, as desired.

it is to be understood that the difference in the pronunciation of these two words consists, in the case of ma-ma, in the production of a preliminary nasal sound before vowel A; whereas the absence ofsuch preliminary nasal sound results in the articulationof the syllabical' sound pa-pa. The usualmethod heretofore followedin sound devices simulating the word"ma-ma has been to produce a soundfinside. a, Chamber otherwise closed except for two sound-emitting openings, one of which (the first or preliminary opening.) as related syllabical annunciation) is smaller, than, the other, and haslb'een constantly open, eventhough the larger opening be closed temporarily, Thus the nasal sound of the letter M is first heard omitted through the, smaller opening before the larger opening is uncovered by its co-operating valve, and then at the, moment the. larger opening uncovered the vowel A follows the consonant M thereby producing. the syllable .ma. The omission of the smaller opening results in the of the syllable, pa.

A distinctive feature of my present invention consists in the provision of means whereby the smaller or. preliminary nasal opening a may be. closed or opened at will, so that a doll equipped with my improved voice device maylbe set to ejaculate either papa or mama, as desired,by the simple expedient of! turning'the nasal valve N, in one direction or the other. a

It is obvious that various well known mechanical expedients may be resorted to for thus covering or uncovering the nasal opening (1 andI do not limit myself to the form of valve disclosedhereinwhich, however, is well adapted to the purpose in that it is simple in structure, and also functions as a closure for this extremity of the throat pipe a. As shown in the accompanying drawings, said valve consists of a hollow cylindrical stem portion n, extending into the throat tube a, beyond the nasal aperture a thereof, and formedwith an opening a, corresponding to said nasal opening a and which may be brought into coincidence therewith, as illustrated in Fig.12, or out of coincidence therewith, as in Fig. 13, of the drawings, the extent of rotat-ive movement of the valve inleither direction being limited by aboss or projection (4 inturned on the throat tube a, and protruding into a segmental slot a formedffor the purpose in said cylindrical portion a, of the valve N, as shown more particularly in Figs. 11, 12 and 13 of the drawings, by reference to which it will be seen that the ends of the slot 173, whencontacting with the boss. a", of the tube a, act as stops to limit movement of the valve in eitherdirection. Incidentally the protrusion of the boss (0*, into the transverse segmental slot 12?, prevents the slipping out or removal of the said cylindrical portion a, of the valve N, from the throat tube a, thereby securing said valveN, in position.

The outer end-of the cylindrical portion n,

pronunciation of the valvev N, is formed with prongs n 12 which project through the disk of the button a", which latter constitutes the handle or linger piece by means of which the valve N, may be manipulated,said button 72%, being intended to protrude, through the back of the doll D, as indicated in Fig. 14, and to be utilized anddisguised-as a possible fastening for a part of the doll clothing, said Fig. l}, also showing in. dotted lines the preferred position of the voice device within the body ofthe doll.

In order to prevent possibility of leakage of air through the disc at, around the prongs a, a, I insert a sealing plug m in the outer extremity ofthe cylindrical port-ion n, of the nasal valve N, as shown more particularly. in Figs. 9 and 11, of the drawings.

An important requirement. to insure perfect operation of a device. of this character where a bellows B, is usedas the air compression chamber, is the complete inflation of said bellows before the start of the retractile, or compressive movement ofitsweighted movable head Z), otherwise the latter may move a considerable portion of its collapsion stroke without perceptibly compressing the air in the bellows, causing partial or complete failure in the pronunciation of the first syllable or its consonant, andv resulting in the sounds ama or apa, or only. the last syllable of either word. Or, to/indicate the trouble in difierent language, the imperfect inflation of the bellows may cause the completion of the expansion stroke of the weighted head b, to create a partial vacuum or tension within the bellows that has to be overcome before actual compression of air is attained, thus impairing initiative sound production as above stated.

I obviate this difiiculty, in my construction of apparatus herein set forth, by providing the movable head 12, of the bellows B, with one or ,more auxiliary air inlet openings 6, b the first, 5, being positioned to coincide with the throat opening a, when the said movable head I), is, at the completion of its expansion stroke, as in Fig. 4:, of the drawings, so as to insure an adequate supply of intake air through the throat pipe a; or an inlet port 6 may be made in the said movable head 6, communicating directly with the interior of the bellows B, when said inlet port 6 is uncovered by the automatic opening of its closure flap. 6*, as also shown in said Fig. 4;, of the drawings, Fig. 9, of the latter showing said flap 6-",

as closed by internal pressure during the compression stroke of the movable head. Z). It is to be noted that in both instances the air inlets b, 12?, are valve controlled inthat. the neck of themovable head I), in one case. acts as the valve to open and close the aperr tune if, in the throat tube. a, and in this respect being-the equi qalent. of. the flap, valve 6 provided for the direct port 6 latter, it is to. be noted, insures an ingof air to the bellows B, even after the inlet a, in the throat tube a, is closed by the neck of the movable member, and up to and during the completion of the expansive stroke of said movable head of the bellows, so that all. tendency of rarefication or" air within the bellows is obviated in a positive manner, the valve 6 closing automatically at the inception of the retractile or collapsestroke of the movable head Z2.
